5tlg: .Stimuli aferra tu in that ettas tant mit making part si its sans.

TO ALL WHOM IT MAY CON-CERN Be it known that I, J. P. JOHNSON, of Macon,in the county of Macon, and State of Illinois, have invented a new andimproved Cultivator; and I do hereby declare that the following is a.full, clear, and exact description` thereof, reference being had to theaccompanying drawings, making a part of this specification, in which-Figure 1 is an elevation of one side of the machine, with portions ofthe wheel broken away to exhibit parts which are behind it.

Figure 2 is a plan view of the machine.

Figure 3 is an elevation ofthe rear end of the machine= Similar lettersof reference indicate corresponding parts in the several figures.

This invention relates to certain novel improvements on cultivators,wherein the ploughs or shovels are attached to a frame that is mountedon two wheels, so as to be drawn by two horses, and wherein a driversscat is applied to said frame in a position which will allow the driverlto guide the ploughs along the rows with his feet.

The object of my invention is to connect together plough orcultivator-beams, which are loosely hinged at their front ends to thecarriage-frame by means of diagonal braces attached by loose4connections to standards rising from said beams, and to apply footpieces to the plough-beams in such manner that the driver, whilst ridingupon the machine, can readily guide the ploughs and control theirmovements along the rows with his feet, as will bevhereinafterexplained. Another .object of my invention is to enable the driver toraise or lower the ploughs or shovels with his feet, in amachinecombining the above-mentioned elements, by suspending the rear ends ofthe shovelsbeams from the axle of the transporting-wheels, by means ofchains passingover pulleys, .and provided with stirrups for the feet ofthe driver, as will be hereinafter explained..

To enable others skilled in the art to understand my invention, I willdescribe its construction and operation. 4 i In the accompanyingdrawings, A. represents Athe axle of two transporting-wheels B B, whichaxle is mainly of wood, its ends being metal pieces, which are bent soas to raise the wooden portion considerably above the hubs of the saidwheels. This will leave plenty of room for the axle `to passunobstructedly over plants undergoing cultivation. The draught-pole C issecured rigidly to the middle of the length of the ax'l'e A, and extendsin rear of this axle some distance, receiving upon its rear forked end aseat, D, upon which the driver sits to manage the machine. In frontofthe axle C is a transverse beam, E, which is secured rigidly to thedraughtpole C, so as to project equal distances from both sides thereof.To this beam the single-trees a a are attached, and near its ends strongpendants are secured, extending downward some distance, as shown at b b.To these pendants b the forward ends of the two forked plough orshovel-beams F F are attached by means of loose joints or links c c,which will allow the said beams to vibrate freely in every desireddirectiom These forked beams are curved at their rear ends, and haveshovels or ploughs UZ d, of any suitable form, secured firmly to them,as shown in the drawings. Between the two forks of each plough-beam F, astandard, G, is rigidly secured at its lower end by means of atransverse bolt, c, which also secures rmly in place, on the inner sideof each beam, a step, g, for the foot of the driver. The standards G'Grise some distance above the carriage-frame of the machine, and areconnected together by means of two diagonal braces Gr Gr', which arecrossed and pivotecl together at the middle of their length, as clearlyshown in fig. 3; These cross-braces are attached to the Astandards Gbymeans of links or eye-bolts, L, which allow the driver to'raise or loweror to move the ploughs in any desired positionwhile the machine is beingdrawn along. Several extra holes are made through the rends of thebraces G G for allowing the eye-bolts on the braces to be adjustednearer or further from the central pivot of these braces. The curvedbraces jj, which are secured to the beams F and to the standards, serveto stay these standards against forward or backward strain. Theplough-beams F F are suspended from the axle A by means of chains t t,which pass through eyes aiixed to the axle A, and are carried overgrooved pulleys upon the rear side of this axle. These chains havestirrups s s attached to their pendent-ends, into which the driver putshis feet when he desires to raise the ploughs free from the ground. Thedrivers seat D is located upon the rear end of the'draught-pole C, inrear of theaxle A, so that the driver, whilst sitting upon hisseat, canmove and controlv the movements of the ploughs with his feet, while hishands are free, and also so that the driver can conveniently get on ando his seat while the machine is in motion.

I have shown that the two forked plough-beams are loosely hinged to thefront part of the machine, so as to allow their rear ends to have a freelateral and vertical play also that the rear parts of these beams areconnected together by means of diagonal braces, so attached as to allowthe driver tol adjust theA plonghs as he may desire during the forwardmovement of the machine. These loose connections allow the plough-beamsto be spread apart, and to be adjusted toward each other; and while thisis the case the braces G G and their standards prevent the plough-beamsfrom turning about their front joints, and keep the ploughs always in anupright position. v

Having described myinvention, .what I claim as new, and desire to secureby Letters Patent, is 1. The attachment ofthe forked plough-beams F F topendants?) b by means of loose joints c c, and the employment, incombination therewith, of the standards G G and diagonal braces G G',steps sgg, and drivers seat D, arranged and operating substantially asdescribed.

2. In combination with plough-beams F, which are attached by looseconnections at their forward ends,`

and sustained in position by diagonal braces G G and standards G G, Iclaim the employment of suspending'- vchains and'stirrups lfor enablingthe driver to raise land lower the ploughs, substantially as described.
